I would like to ask why the signature information of the application package failed to be verified and could not be shared on WeChat. AppSecret error, inconsistent signature, etc.

AppSecret error: AppSecret is an important certificate of the application, which is used for authentication when calling the interface. If it is not filled in correctly, the verification will fail.

Inconsistent signatures: The signature information of the application package is used to verify the identity of the application. When the signatures are inconsistent, the WeChat server will think that the application is not what the developer claims, so it will refuse to share.
